Local jazz musical will be the focus of the ninth annual Old Algiers RiverFest™ September 28-29, which will be held at the corner of Belleville Street and Patterson Avenue at the river from 11 a.m. to 6 p.m. Old Algiers RiverFest™ is the only free festival in New Orleans that focuses on traditional jazz and its connection to the river. And this year, it coincides with the last free weekend of ferry service.
